Blikkies's code will not work,it will not display images.
By the way you should post this question in ASP.NET forum.

But you have to take the images and paste it into your project, then the code should look like this:
protected void Page_Load(object sender, EventArgs e){
Response.Write (@"<table border='1'>");
Response.Write (@"<tr>");
Response.Write (@"<td><img src='at.jpg'></td>");
Response.Write (@"<td><img src='try.jpg'></td>") ;
Response.Write (@"</tr>" );
Response.Write(@"</table>");}
To able the client to see the images, the images should be in the Project folder.

One thing i want to ask...
I assign image path to some string variable like this:
string path = "C:\at.jpg'
and apply this:
protected void Page_Load(object sender, EventArgs e)
{
Response.Write(@"<table border='1'>");
Response.Write(@"<tr>");
Response.Write(@"<td><img src=path></td>");
Response.Write(@"<td><img src='D:\try.jpg'></td>");
Response.Write(@"</tr>");
Response.Write(@"</table>");
Then it does not display image neither it shows any error message. Why so?Please help..

One thing you must know,you CAN'T load image which is located outside project's folder,because this is ASP.NET,buy the way your image control is HTML Image and still this doesn't provide you possibility to load images as you are trying.
Why you don't create one folder inside your project and programmatically save images in that folder and then load it.

Because your image should be in the project, you cant attatch images that out side the project. I take it that you did window form before moving to asp, in a window application you can specify source of image like "C:\aaa.jpg" but in html or asp its different ex. let say all your files including asp and C# files is in "c:\inetpub\wwwroot\Myproject", you have to insert your image aaa.jpg into "c:\inetpub\wwwroot\Myproject" then your code should look like this
<img src="../aaa.jpg" />
Hope this help you.

You have to save image inside project folder,and insetad giving path to src property then just write name of image.
Response.Write ("<td><img src='at.jpg'></td>");<br />
Response.Write ("<td><img src='try.jpg'></td>") ;

Also, for you to do this at all, is totally wrong. That's not what ASP.NET is for, it's better than that.

I have an application with CrystalReports. The app works fine on the dev machine but fails on the production machine because of some Crystal .dll not loading. I have set Copy Local to true for all the crystal reference files therefore they are copied to the bin folder. I copy all files from the bin folder to the production machine but still fails. Any idea what else I should do?

You have to use the Crystal Reports redistributable msi and build an installer or have the user manually install the Crystal Redistributable for your given version. At least this is how this problem used to be fixed. I haven't deployed Crystal in a while.

Using/Deploying crystal reports is a real pain

It just takes experience. There is a common theme in aviation that there are many pilots with 500 hours experience. Some have the same hour 500 times and some have an actual 500 hours. I think Crystal is the same way. The intro and learning curve is so steep that people initially only learn the hacks and then repeat thus giving it a bad rap. While there are many things I can do in Dev Express that I can't do in Crystal it isn't exactly a cake walk there either.

Thanks a bunch! I downloaded the merge module from
http://resources.businessobjects.com/support/additional_downloads/runtime.asp#09[^]
for VS 2005. I followed the steps in the word document file to create a setup project and add the downloaded module using Add, Merge Modules. Everything works fine.
My next question is, do I have to bundle every app which has Crystal Reports with this module or once the module is added, I do not need to do it again. In other words, does it work similar as adding a .dll to GAC?

It has been a long time since I have made an installer but the msi should not reinstall itself it has already been installed. I would just leave it in the installer and it would work fine every time. But yes, if you install another app on the same computer with the same version of Crystal you will not need another msi, however, same is a word that will bite you on the rear, even in the .NET world.

Hi
I'm working with Mono.Cecil for IL Manipulation and find some articls like this[^]
but i didn't found any useful article about what's OpCodes and expain each OpCode item.
can anybody help me ?
thanks

Follow these easy instructions.- Go to http://www.google.com
- Type opcodes site:microsoft.com for your search criteria.
- Click the link entitled "OpCodes (System.Reflection.Emit)
That'll list the opcodes for you.
If you want to know how each works, read Standard ECMA-335[^].

This sounds like a job for the Specification Pattern[^]. This would let you inject your own logic into a more general method, reducing the need for code duplication.
There's a video presentation here[^], although be warned: JP Boodhoo goes about a million miles per hour and it took me several watchings just to understand that I already knew what he was talking about!

To whom it may concern,
I have a button onclick event, where I disable the button (setting its enable property to false), have some process which takes some time, and then reenabling the button at the end of the onclick event function. My query is that the onclick event is fired even though the button has been disabled (clicking more than once while the button is still disabled).
The following snippet illustrates the problem. Any solutions are appreciated.
private void button1_Click(object sender, EventArgs e)
{
DateTime d1, d2;
TimeSpan t;
d1 = DateTime.Now;
if (button1.Enabled == false)
return;
button1.Enabled = false;
while (true)
{
d2 = DateTime.Now;
t = d2.Subtract(d1);
if (t.TotalMilliseconds > 2000)
break;
}
label1.Text = (count++).ToString(); // shows the number of times the function has been called (count is a global variable)
label1.Refresh();
button1.Enabled = true;
}
Thanks in advance

Hmmm... very strange process. I assume you have done so just to play around with things.
your code is currently being executed on the UI thread when the button is clicked. This means that until the event process has been complete then the form will not be updated. You can use functions like Update or Refersh (like you have with label1) in order to make a change to the display/layout of the form/control. If you do not do so then it will only occur once the function is complete. So basically, even thou you are disabling the button in the function it will not be applied until the function is complete, but by then you have already enabled the button again.. So no change will be applied. You could try refreshing the button after you disable it and that should work (not tried before thou).
I would recommend that you take a look into Background Workers[^] as these can be used to process longer functions on a separate thread, thus freeing up the form for continued user interaction. There are alos a number of Timer Components[^] you may want to have a look at too.

return;
Unless you are planning to 'emulate' the button click by calling the function specifically from code then you should not need to include that code. If you only ever use function when button is clicked by user than this should only ever evaluate to be false anyway

Thanks for your quick reply. The main reason of disabling the button when the user clicks the button is that the code within the event will be executed only once. Once the code has been executed the button will be reenabled allowing the user to click the button. The problem is that even though the button has been disabled, and the program is still in the event function, the event will be fired once completed (given that the button has been clicked while it was disabled). It seems that the event queue is not cleared when the button has been disabled. The label shows the number of times the event has been called.
To ensure the event is only called once (while the button has been disabled) i have included this statement:
if (button1.Enabled == false) return;
I could use timers or threads, but I try to avoid them.
Thanks

Timers is debatable, but not using threads (especially with the ease of Background Workers) is a big mistake. Like I have said, running code that will take more than a second (or even less) should not hold up the UI thread, this leads to bad user experience as in most cases the application will appear to crash/freeze and more than likely display the "Not Responding" message, which just makes the application look bad.
When a process is called on the UI thread then the form is not automatically updated until control has been return to it (so to speak). Unless you specifically 'interrupt' the function and tell it to do so.
Try my suggestion of using Refresh after you disable the button (which should be your first two lines within the event BTW) and see if that stops multiple clicks.
And if your counting the number of button clicks during the actual process then you should reset the counter to 1 at the start of each click, otherwise you are storing number of button clicks since form was created. - Sorry, a moment of stupidity 
I strongly suggest attempting to use a background worker if you have not done so before.

Well, that's interesting. It's like the click is cached and processed once the control is re-enabled.
I used the following:
private void button1_Click ( object sender , System.EventArgs e )
{
System.Windows.Forms.Button button = sender as System.Windows.Forms.Button ;
System.Console.Beep() ;
if ( ( button != null ) && ( button.Enabled ) )
{
button.Enabled = false ;
System.Threading.Thread.Sleep ( 2000 ) ;
button.Enabled = true ;
}
return ;
}

hi
thanks for your quick reply. i have tried the code, but unfortunately it does not work. if you click the button twice within two seconds, you would hear two beeps meaning that the event has been fired, even though the second click was on a disabled button
this is a very strange issue, i guess the event queue is not cleared. if one does not enable the button at the end of the function, only one event will occur. for instance the following has the same consequences:
private void button1_Click(object sender, EventArgs e)
{
button1.Enabled = false;
timer1.Enabled = true;
}
private void timer1_Tick(object sender, EventArgs e)
{
timer1.Enabled = false;
System.Console.Beep();
Thread.Sleep(2000); // could be a blocking function
button1.Enabled = true;
}
thanks

The problem here is you are disabling the button and then 'freezing' the UI thread.
So when you click the button, or anything in the form then that click can not be processed until the form unfreezes. The form will only unfreeze once the thread sleep has finished and the Tick event is complete (at which point the button is re-enabled) so the 'Click' is effectively done on an enabled button.
Basically it is the form that is processing your click and is can only do so when it the UI thread is free to do so.
